I have a group of 7th graders that are looking to build a scale model of a LEKO / Spotlight. This will be much smaller that a true Leko, but they are hoping for the same functionality ( crisp edges with adjustable shape to the spot ). They will be using this on a fairly short scale of around 25-30 feet at a max range. I have been looking for specs, etc but really can only find some drawings, etc.
They were hoping to be able to use an LED flashlight as the light source as it already has the parabolic element, but I'm not sure if that will suffice. Also not sure how to find the focal point distance needed for the gate. We have a set of plano-convex lenses to use that we had from a old science teacher. According to the label on the box, they are 50 mm plano-convex lenses with a 200 mm focal point.
I'm no expert on this stuff, so definitely learning as I go along with the kids.
Any advice or places to find good specs would be great!
